Cheers Adrian (I will get round to calling you one day, and when I do you'll regret it, I'll pick your brains about everything!)
Yep replaced the indicator switch cam and complete column harness aswel and what I thought was both the hazzard and flasher relays (the reprods of these are quite small pod types and are very similar and have 2 spade terminals) but when I replaced the dash harness I noticed their was a longer thinner cyclinder type relay (which I think has 3 spade terminals from memory) nearest the column which I've yet to test/replace, you'll probably gonna tell me that this is the flasher relay
I'll post/text some relay pics over the weekend to see what you think and failing that I might just take you up on your kind offer!
Cheers
